Abstract (en)
[origin: EP2192276A2] A gas turbine engine has an engine casing component, such as a mid turbine frame system, which may includes an outer case (30) surrounding a spoke or strut casing (32). Load transfer spokes (36) of the spoke casing (32) extend between the outer case (30) and an inner case (34) of the spoke casing (32). A bearing housing (50) supported by the engine casing may include a fuse arrangement (58; 60) for isolating bearing seizure loads from the engine casing. A seal arrangement may be provided to centralize the rotors after the fuse fails. The mid turbine frame may be provided to have a desired flexibility through the configuration of the casing and bearings in design.
